Description

A kind of device of automatic-closing valve

The utility model relates to a kind of device of automatic-closing valve

In daily life, people often forget the phenomenon of Guan Shui, turn out the gas, cause unnecessary water resource waste and gas leakage accident.For this reason, people have produced some reclosers, and the present automatic switch device needs electricity consumption and battery, when have a power failure or battery cause after using up can not automatic-closing valve.And can cause the disaster accident because of the generation of electrical spark.

The purpose of this utility model is exactly to produce a kind of device of automatic-closing valve, and it need not electricity or battery, can automatically lock the time of throttle down according to people's needs, handling safety.

The utility model is achieved like this, it is by shell, the assembly frame, timer, timer monopodia copper sheet, contact bar, the contact pendulum, gear reducer, line shaft, internal gear, external gear, clockwork spring, cursor, curved bar is formed, curved bar one end connects valve switch, the other end connects cursor, the other end of cursor connects line shaft, line shaft connects internal gear, external gear, gear reducer and clockwork spring, the contact is put an end and is connected gear reducer, the other end is fixedlyed connected with contact bar one end, the contact bar the other end withstands on the timer monopodia copper sheet, all component all is assembled on the assembly frame, assembly frame and timer are separately fixed on the shell, usually external gear on the line shaft and gear reducer rotate under the elastic force of clockwork spring drives, bump contact pendulum, the other end of contact bar is timed device monopodia copper sheet and withstands, can not swing, produce lock function, the line shaft clockwork spring can not be drawn back, in timer monopodia copper sheet, contract, leave contact bar, then contact pendulum swing fast under the effect of spring force, line shaft is rapidly to rotating on one side, the drive cursor rotates, the rotation of cursor pulling curved bar, thus valve is tightened, and the work of closing is finished, when time switch is started, timer monopodia copper sheet is outer once more to be scratched, and the contact bar top can not swing near copper sheet once more, and Xiang Kaiqi side pushes wealthy door bar open, this moment, the line shaft internal gear rotated, external gear is motionless, and clockwork spring tightens, and whole device is in the locking working state.In the time need closing in advance, time switch is backed starting point, valve is closed automatically.Usually timer all is that electrical equipment is played time action, and the utility model can also work to open and close valve after repacking, that is: shed two original copper cash and not with the participating of copper sheet, stay a band copper sheet and participate.The plastics openning that closes out outside the copper sheet position inserts contact bar to be close to copper sheet to play to timely lock and opens on-off action, has separated closing function otherwise contract in the copper sheet with contact bar.

The utility model adopts timer controling time, utilizes clockwork spring driving work, need not electricity or battery, and is easy for operation, safe and reliable, except that the control of extensive use water, gas valve, can also be used in the switch control of other machinery, chemical industry equipment.

Below in conjunction with accompanying drawing the utility model is further described below.

Accompanying drawing 1 is a work schematic representation of the present utility model.

Shell 2, assembly frame 3, timer 4, timer monopodia copper sheet 5, contact bar 6, contact pendulum 7, gear reducer 8, internal gear 9, external gear 10, line shaft 11, clockwork spring 12, cursor 13, curved bar in the drawings, 1,

As shown in Figure 1, the utility model is by shell 1, assembly frame 2, timer 3, timer monopodia copper sheet 4, contact bar 5, contact pendulum 6, gear reducer 7, internal gear 8, external gear 9, line shaft 10, clockwork spring 11, cursor 12, curved bar 13 is formed, curved bar 13 1 ends connect valve switch, the other end connects cursor 12, the other end of cursor connects line shaft 10, be connected with internal gear 8 on the line shaft, external gear 9, gear reducer 7 and clockwork spring 11, the contact is put 6 one ends and is connected gear reducer, fixedly connected contact bar 5 one ends of the other end, the contact bar the other end is pulled timer monopodia copper sheet 4, loose mail all is assembled on the assembly frame 2, assembly frame 2 and timer 3 are fixed on the shell 1, external gear on the line shaft and gear reducer rotation under the elastic force of clockwork spring drives at ordinary times, bump contact pendulum, make an end of the contact bar that the contact lays out be timed device band foot copper sheet and withstand, can not swing, produce lock function.In timer monopodia copper sheet, contract, leave contact bar, then contact pendulum swing fast under the effect of spring force, line shaft drives cursor and rotates rapidly to rotating on one side, the rotation of cursor pulling curved bar, thus valve is tightened, the work of closing is finished.

When time switch is started, twice outer scratching of timer monolithic copper sheet, withstand contact bar can not about pendulum, line shaft is pushed valve lever open to opening gas side, this moment, the line shaft internal gear rotated, external gear is motionless, clockwork spring tightens, whole device is in the locking working state.

Claims (2)

1, a kind of device of automatic-closing valve, it is by shell, the assembly frame, timer, timer monopodia copper sheet, contact bar, the contact pendulum, gear reducer, internal gear, external gear, line shaft, clockwork spring, cursor, curved bar is formed, it is characterized in that curved bar one end connects line shaft, connect internal gear on the line shaft, external gear, clockwork spring and gear reducer, the contact is put an end and is connected gear reducer, the other end is fixedlyed connected with contact bar one end, the contact bar the other end withstands on the timer monopodia copper sheet, all component all is assembled on the assembly frame, and assembly frame and timer are separately fixed on the shell.
